The hydraulic cylinder means includes: a fluid cylinder 42 which has therein a piston 43. This piston 43- preferably has a rubber outer coating 44 tov provide a satisfactory piston seal and an inner section of metal or other hard material 45 into which fits a rod means 47. The rod means 47 may be composed of two rod sections 48 which are securely attached to the member 45 or in some cases the rod means 47 may be a single rod.

extending through the piston 43 and having its ends 49 protruding outwardly of the cylinder 42. The ends 49 of the rod means 47 are preferably threaded to receive the nuts 50 which hold the vertical section 52 of the carrier frame 51 in engagement with the rod means 47. The carrier frame 51 also includes a substantially horizontal member 53 which has pivotally connected thereto the upright arm 27. The upright arm 27 is further connected to the horizontal member 54 by braces 56 and 57.

In the movement of the piston 43 back and forth in the cylinder 42, the carrier frame 51 is likewise moved back and forth. This back and forth movement of'the carrier frame 51 is transmitted to the arms means 26 which because of the swivel mounting means 19 enables the nozzle 10 to likewise effect a back and forth move ment in an arcuate path as illustrated particularly in Fig. 2 wherein the solid line of the nozzle 10'illustrates one position while the dotted line illustrates the extreme other end of the travel of the nozzle 10. Since'the support means 16 is fixed it is necessary to provide for a backward displacement of the housing 31 during this arcuate travel of the nozzle 10. This backward. travel of the housing 31 is seen in Fig. 4 wherein the solid line indicates the position which the arm 27'would assume at one end of the arcuate travel of the nozzle 10 while the dotted line of the arm. 27 and thehousing 31 indicates the central point between the extreme position of travel of the nozzle 10. To provide for thebackward movement of the arm27 and the housing. 31the end members 52 are so mounted rotation about the rod means 47 Fig. l.

asto permit a limited as can best be seen in For regulating the movement of the piston 43. in the" cylinder 42 a valve means 60 is provided. This valve means 60 includes a valve cylinder section 61 which has two inlet openings 62 and 63 and two outlet open ings 64 and 65 with suitable piping connections therewith. The fluid inlet and piping 62 and 63 have corresponding pipes or tubes 62A and 63A respectively. Likewise the outlet openings or tubes 64 and 65 have corresponding tubes or pipes 64A and 65A respectively. The pipes 62A, 63A, 64A and 65A lead from the upper side of the cylinder 61 to the lower side of the cylinder 42 although it will be appreciated that any suitable positioning of the tube with respect to the two cylinders may be utilized. Within the cylinder 61 are two valve members 67 and 68 which are connected by a hollow tube or sleeve 69. Within the hollow tube or sleeve 69 is a slidable member 71 having a shaft means 72 associated and connected therewith. The outer ends 73 and 74 p of th eshaft 72 are connected to a bracket 75 which is similar to the carrier frame 51 of the main fluid' cylinder 42. Above the bracket 75 is a valve control means 76 which includes a lever 77. pivotally mounted at pivot I 78. This pivot 78 is simply a bolt and swivel arrange amine"? 3 ment on a bracket of U-shape indicated by the numeral 81' in Fig. 4. A clevis or similar bolt arrangement 83 is provided at the end of the lever 77 for connection with the bracket 75. At the upper end of the lever 77 is a counter balancing weight 85 which is mounted with set screws 86 and may be supplemented with movable weights 87 to provide additional counter balance for the valve control means 76.

The operation of the: valve control means 76 can best be understood by referring to Fig. 1 and assuming the operation tostart from. a-position with the piston 43 in the left hand side of the cylinder 42 as shown in Fig. 1. When the piston 43 isin the position shown in Fig. 1, the valve members,67. and are closing off the openings of tubes 63 and 64 so that air or other fluid is admitted through the line 62 and thence through the cylinder 61 to the line or tube 62A whereupon the fluid. enters the cylinder 42v to cause the piston 43 to move to the right. The valve control means 76 remains in the position shown in Fig. 1 until the left end of the tripping means 89 contacts the lever 77 to move it pivotally about its pivot 78. When the lever 77 reaches a substantially vertical position by reason of the contact with the end 90 of the tripping means 89 the counter-balancing weight 85 causes the lever 77 to move to the extreme right position limited in its movement only by being stopped by the abutment of the bracket 75 with the right end. of the valve means 60. This movement of the. valve control means .76 causes the bracket 75 to move to the left carrying with it the slidable member 71 which moves through the tube 69 to the left position whereby it contacts and moves the valve member 67 until it contacts the end of the cylinder 61. Since the valve members 67 and 68 are interconnected by the tube 69 both of them are moved upon the movementof one or the other so that when valve member 67 is moved to the extreme left position the valve member 68 likewise moves. ment of the valve members 67 and of the openings of tubes 62 and 65 the tubes 63 and and an opening of 64 whereby fluid is then admitted to the right end of the cylinder 42v through the inlet tubes 63 and 63A. The operation of the valve control device 76 will then" function in the opposite manner as the piston 43, moves to the left with air or hydraulic.

fluid exhaustingdhrjough tubes 64A. and 64. Thus, after limited movement of the piston. 43 to the left,

the end 91 0f the tripping;v means 89 will cause the lever 77 to move to the. left until it reaches a substantially vertical position or just to the left thereof. at

which point the weigts 8.5 and 87 will cause the lever 77 to move to the left and assume a position as shown in Fig. 1. This leftward movement of the lever 77 is stopped by the ahutmentof the left portion of the bracket 75 with. the valve means 60 or by the contact of the'piston 6.8. with the, right end of the cylinder 61 due to its'being urge'd'by the slidable member 71. Automatically then the fiow of piston fluid to the piston 43 is reversed. Thus, it can be seen that the admission of actuating fluid to the cylinder 42 is controlled so that the actuating fluid is admitted to the opposite ends of the cylinder, 42 alternately, which admission is maintained automatically 7 by reason of I the valve control means 76 and, related structure.

It will be appreciated that the mud or other fluid. distributed from the nozzle, 10 is fed from a slush or mud pump, not shown, to the lower end of the pipe 17,

thence upwardly through the pivot member 25, tubes 23, block 22 and'jthen outwardly through the nozzle 10;

This" flow of mud will be maintained continuously, if'

desired, during the oscillation thereof.
